Obsidian Eradicators are mobs inside the Temple of Ahn'Qiraj. They pull singly. They can drain mana from all mana users in range. It seems that they choose 16 candidates to drain mana from as soon as aggro is acquired. They will cast an area effect Shock Blast on everyone within 30 yards (6.5K nature damage) if their mana is allowed to reach 100%, so they must be drained of their mana with Mana Burn, and Drain Mana. Viper Sting is not recommended as a mana drain, because it will take up valuable Debuff real estate, even if you only have 3 warlocks and 3 priests draining his mana. Viper Sting is simply not needed.

An Obsidian Chunk will fall to the ground near the slain Obsidian Eradicator.


A highly recommended strategy is to have 3-5 warlocks using Drain Mana, and 3-5 priests using Mana Burn while one or more druids heals the main tank. This enemy does not hit hard, and the main tank doesn't require much healing. Everyone else in the raid who is not healing or draining mana should be doing DPS.

The mana burn targets a mana user randomly and then burns mana from ALL mana users in a small radius around that person. Thus it is important to spread out your mana users, especially if you have limited mana draining capacity.



Obsidian Eradicators will respawn 30 minutes after they are killed.
